How to run a function automatically on scheduled Intervals?

Question

I am developing a plugin for a Wordpress website in which I would like to generate a report on the first day of every month and send it to the users/admin.

Creating a Cron job in the server would be a perfect solution but there are few hurdles in creating Cron Job programmatically as the procedure differs from Server to the server(I guess). So I am thinking of a WordPress function instead of creating a Cron Job in the server that does this job.

Do let me know if you guys have any idea about it.

I found the solution myself. I hope it would be helpful for others.

function do_this_in_an_hour() {

 $postid = "1"; //Supply post-Id here $post->ID.
    wp_update_post(array(
        'ID'    =>  $postid,
        'post_status'   =>  'draft'
        ));     
}
add_action( 'my_new_event','do_this_in_an_hour' );

wp_schedule_single_event( time() + 7200, 'my_new_event' );

// time() + 7200 = two hour from now.
